FT EMS SWC V2

INTRODUCTION

This is an upgrade to V1 of the FT EMS SWC. This frame was designed to help manage the electronic components required for a switchwire conversion (SKR Mini E3, Creality boards, Raspberry Pi, U2C boards etc,..). Typical conversions have you squish all these components at the rear of the printer making it tough to mount not to mention cable manage.

THE DESIGN

This frame is ideally used when converting an Ender 3 V2 to become a Voron Switchwire or Enderwire as they are sometimes referred to. 

BOM

This mod does need to be printed on a bed that is capable of printing 300mm. Since these parts are not installed in the heated chamber they can be printed in PLA/PETG but we would still recommend using ABS or ASA for overall strength and as recommended by Voron design.

All parts are oriented correctly to just slice and print without the need of supports.

Additional parts necessary are: -

1. 1 x heatset insert to hold the lid down on the cable duct
2. 1 x M3x6 BHCS screw for the cable duct lid
3. 9 x M5x10 BHCS screws to mount the frame
4. 9 x M5 T Nuts to secure the frame to the extrusions
5. 4 x heat inserts for the front 6020 fan
6. 4 x M3x8 BHCS screws to mount the front fan onto the frame mount
7. 2 x M3x20 BHCS screws to mount the frame support

FT EMS solutions all use the same size hex design. You will need to download and print the mounts you intend to use from the FT EMS Mounts Repository. We support a variety of boards from BTT SKR, BTT Manta, Mellow, Cheeta etc,… if there happens to be a board you intend to use that is not currently supported please reach out on our Discord Fizzys 3DPrinting.

INSTALLATION INSTRUCTIONS

EMS is designed to be extremely flexible as to let the user decide what hardware to use on the printer. Therefore we have created a mounts repository where power supply, controller board, expansion board and single board computers (Raspberry Pi) mounts are stored. Please visit our mounts repository to download universal cable ducts and mounts for the hardware you intend to install - https://www.printables.com/model/558357-ft-ems-mounts-repository

Which hex mounts do I need? Here is a breakdown of what each are used for: -

1. Mount A = hole directly in the center of the hex and the screw is inserted from the mount side
2. Mount B = hole is with a 5mm offset and the screw is inserted from the mount side. Depending on which direction you need the offset you can rotate the hex so its actually 5mm offset in 6 directions!
3. Mount C = Cable tie in the center of the hex in the vertical orientation
4. Mount D = Cable tie in the center of the hex in the horizontal orientation
5. Mount E = These are used for electronic mounts that have a heat insert in them. The screw will go through the center of the hex from behind into the mount. These are typically used for SSR and some PSU mounts.
6. Mount F = These are used for electronic mounts that have a heat insert in them. The screw will go through the center of the hex from behind into the mount. These are typically used for SSR and some PSU mounts.
7. EMS Bolt = this is used for awkward mounts and load into the channel on the electronics mount with an M3 heat thread insert preloaded. These work in combination of Mount E and F.

With the hex mounts explained, below are the recommended steps to follow to get FT EMS for your Enderwire installed: -

1. Download and print all the parts within this model. The 6020 fan is highly recommended to be relocated at the front with it mounted in the intake orientation to blow fresh air over the controller boards. If you happen to have a 2nd 6020 fan that can also be installed at the rear but oriented as exhaust.
2. Visit the  FT EMS Mounts Repository, download and print the required mounts for the electronics you intend to use. Typically at minimum that would be an SKR Mini E3 and a Raspberry Pi.
3. The EMS frame
   1. Prepare the frame by mounting the LSR-350-24V PSU using the mounts to the board.
   2. Mount all the required electronics using the correct mounts from FT EMS Mounts Repository prior to mounting the frame extrusions.
   3. Insert the 9 M5 T-Nuts to the correct location and screw down the EMS Board to the frame.
   4. If the front skirts are already installed, remove them. Install the Frame Supports and tighten - this is to provide extra rigidity to the frame once fully installed. 
4. Front fan installation
   1. insert 4 x heatsets into the 6040 (ensure that the inserts are on the front side of the fan as this will be installed as an intake fan)
   2. Mount the fan to the 2 screws that hold on front skirt.
